teemperor added a comment.
The whole information we have "@_ZTI4Base = external constant i8*", that there
is no metadata and that we call dynamic_cast on it. I don't see a better way
for detecting this than actually checking if we are trying to retrieve RTTI
info as a global variable. But I agree that the check itself could be more
robust. Looking at the code for the demangler I don't see any good way that
fits our use case though (e.g. no `isTypeInfo` or something like that). The
only alternative I see for that would be to implement our own mangling
detection and then just have a simple check if the mangled name is type
information related (e.g. `startswith("_ZTI")` and whatever the MS equivalent
its). But that wouldn't be better than what we have now.
